A contact rail connector is connected to the opposing ends of the contact rails of two successive contact line rails, electrically and mechanically connecting the contact rail ends of the contact rails, and having cover elements attached at the opposing rail ends of the contact line rails of two successive contact line rails, covering the contact rail connectors and displaceable relative to an intermediate element. In order to provide an arrangement for attaching two successive contact line rails that is simple to produce and allows uncomplicated assembly, the intermediate element is attached at each of the opposing rail ends of the contact line rails to be connected together, and the cover elements are attached to the intermediate elements.

Abstract: An apparatus for making a cold-pilger-rolled tube has two grooved pilger work rolls rotatable in a roll frame about respective axes to compress a tubular workpiece moving in a travel direction around a mandrel extending in the direction between a nip formed between the grooved rolls and anchored upstream of the nip in a thrust block. An outside diameter of the workpiece is measured downstream in the direction from the rolls as the workpiece passes through the nip, and an actuator engaging one of the rolls relative the other of the rolls shifts it transversely to the travel direction as the workpiece passes through the nip in accordance with the measured outside diameter for maintaining a uniform outside diameter of the workpiece.

Abstract: A device for controlling a motor-driven hoist, includes a housing and a control unit supplied with electric energy from a power source and secured to the housing. The control unit has control elements operable from outside the housing between an inactive ready position and an active position for delivering control signals. A transmitter is supplied with electric energy from the power source and receives the control signals from the control unit for wireless transmission of the control signals to a receiver, which is operatively connected to a power controller of the drive of a motor-driven hoist. An activation switch is so operatively connected to the power source that actuation of a control element initiates a supply of electric energy from the power source, whereas the supply of electric energy from the power source is cut, when the control elements occupy their ready position.
